Oh unfortunately there's no interesting tales in a rural area like this lol. I needed a job, stumbled on this listing, sent off an email, got told to swing by the shop some time. Most people here wear at least a little of everyone else's hats. I emulse and burn screens, weed out lots of vinyl, cut and grommet banners, help cover graphic design, and as far as actually making shirts and hats I'm mainly just on the heat presses with the vinyls and transfer films.
And there is, sorta. While our shipping goes through EasyPost, we rarely interact directly with it. Instead our shop uses a web app called Printavo to manage orders. After feeding it the package details it interfaces with EasyPost (very helpfully autofilling the customer's details from the invoice) and displays all available shipping options from USPS, UPS, and FedEx along with prices for all of them. Sometimes the cheapest shipping varies box by box, but in my experience it's always either USPS Priority Mail or (more often) FedEx Ground. And never, ever anything UPS.
Kinda confusingly, I've never seen any of that info on EasyPost itself, just Printavo's wrapper around it.
